Differences between DVD5, DVD9 and Blu-ray Disc

2. Laser Technology

Lasers are used in both media to read the information on the disc. DVD5 and DVD9 use a red laser at 650nm wave length to read DVD discs while Blu-ray Disc uses a blue laser to read the stored information. Blue laser wave length is shorter than the red laser which allows for closer and more precise reading of disc information.

3. Image Resolution

Image resolution represents the number of vertical lines times the number of horizontal lines of light in a picture, like 480, 720 or 1080. The higher the number, the more superior the picture. DVD5 and DVD9 have a standard resolution of 480 or 520. While, Blu-ray Disc has 1080 HD resolution.
